The device also comprising a motor assembly disposed within the housing, the motor assembly including a motor case and a motor shaft, the motor shaft configured to rotate one of the seal assembly or the actuator shaft. ## Claims ### Claim 1 A device comprising: a housing having a longitudinal dimension; a linear actuator including a casing coupled to the housing and an actuator shaft having an exterior surface and configured to be longitudinally translated relative to the casing; a seal assembly engaging the housing and sealingly engaging the exterior surface; a motor assembly disposed within the housing, the motor assembly including a motor case and a motor shaft, the motor shaft configured to rotate one of the seal assembly or the actuator shaft; and a first seal retainer coupled to the housing; wherein the seal assembly includes a seal case, an inner seal sealingly engaging the exterior surface, and an outer seal sealingly engaging an inside surface of the housing. ### Claim 2 (depends on 1) The device of claim 1, wherein the seal assembly includes a ring gear, the ring gear movably coupled to the motor shaft. ### Claim 3 (depends on 2) The device of claim 2, wherein the seal assembly sealingly engages an inside surface of the housing. ### Claim 4 (depends on 1) The device of claim 1, further comprising a second seal retainer coupled to the housing. ### Claim 5 (depends on 4) The device of claim 4, wherein a distance between the first seal retainer and the second seal retainer is configured to allow the seal assembly to translate along a longitudinal axis of the actuator shaft. ### Claim 6 (depends on 1) The device of claim 1, wherein the motor case is stationary relative to the housing. ### Claim 7 (depends on 1) The device of claim 1, wherein the motor shaft is movably coupled to the actuator shaft. ### Claim 8 (depends on 7) The device of claim 7, wherein the motor assembly includes a motor gear coupled to the motor shaft and the actuator shaft and the motor gear include mating splined surfaces. ### Claim 9 (depends on 1) The device of claim 1, wherein the motor case is movably coupled to the housing allowing linear translation of the motor assembly relative to the housing, and the motor shaft is fixedly coupled to the actuator shaft. ### Claim 10 (depends on 9) The device of claim 9, wherein the motor case and the housing include mating splined surfaces. ### Claim 11 (depends on 1) The device of claim 1, wherein the motor assembly includes a gear box. ### Claim 12 (depends on 1) The device of claim 1, wherein the seal assembly is configured to maintain separation of fluids between an interior of the housing and an exterior of the housing. ### Claim 13 A downhole tool assembly system, the system comprising: a tool housing including: a housing having a longitudinal dimension; a linear actuator including a casing coupled to the housing and an actuator shaft having an exterior surface and configured to be linearly translated along a longitudinal axis relative to the casing; a seal assembly engaging the housing and sealingly engaging the exterior surface; and a motor assembly disposed within the housing, the motor assembly including a motor case and a motor shaft, the motor shaft configured to rotate one of the seal assembly or the actuator shaft; wherein the motor case is movably coupled to the housing allowing linear translation of the motor assembly relative to the housing, and the motor shaft is fixedly coupled to the actuator shaft; and wherein the motor case and the housing include mating splined surfaces. ### Claim 14 (depends on 13) The downhole tool assembly system of claim 13, wherein the tool housing is a drillstring tool or a wireline tool. ### Claim 15 (depends on 13) The downhole tool assembly system of claim 13, wherein the seal assembly includes a seal case, the seal case retaining an outer seal that sealingly engages an inside surface of the housing and the seal case retaining an inner seal that sealingly engages the exterior surface. ### Claim 16 (depends on 13) The downhole tool assembly system of claim 13, further comprising a first seal retainer and a second seal retainer, the first and second seal retainers coupled to the housing, wherein a distance between the first seal retainer and the second seal retainer is configured to allow the seal assembly to translate along a longitudinal axis of the actuator shaft. ### Claim 17 (depends on 13) The downhole tool assembly system claim 13, wherein the seal assembly includes a ring gear, the ring gear configured to be rotated by the motor assembly. ### Claim 18 A device for a downhole system comprising: a housing having a longitudinal dimension; a linear actuator including a casing coupled to the housing and an actuator shaft having an exterior surface and configured to be longitudinally translated relative to the casing; a seal assembly engaging the housing and sealingly engaging the exterior surface; and a helical cam assembly having a first portion coupled to the actuator shaft and a second portion coupled to the housing, wherein the helical cam rotates the actuator shaft when the actuator shaft is translated; wherein the seal assembly includes a seal case, an inner seal sealingly engaging the exterior surface, and an outer seal sealingly engaging an inside surface of the housing; and wherein the seal assembly is configured to maintain separation of fluids between an interior of the housing and an exterior of the housing. ### Claim 19 (depends on 18) The device of claim 18, wherein the first portion is integral with the shaft. ### Claim 20 (depends on 18) The device of claim 18, further comprising a first seal retainer and a second seal retainer, the first and second seal retainers coupled to the housing, wherein a distance between the first seal retainer and the second seal retainer is configured to allow the seal assembly to translate along a longitudinal axis of the actuator shaft.
