Systems and methods for torque isolation valve actuator

A torque isolating valve actuator comprising:

• an actuator housing comprising a first housing channel and a second housing channel;
• a nut housing partially disposed within the first housing channel and the second housing channel wherein the nut housing slides along the housing channel and the nut housing comprises an actuator end and a stem end, and a plurality of guide channels formed in the nut housing which extended parallel the axis of the housing;
• rollers within the nut housing;
• a screw shaft aligned axially through the rollers in the nut housing wherein the nut housing is configured to move along the screw shaft;
• a first rod recessed in the first housing channel configured to receive the distal portion of the nut housing and a second rod recessed within the second housing channel configured to receive the distal portion of the nut housing and connected to the actuator housing and positioned outside the nut housing and passing through the guide channels wherein the first housing channel, the second housing channel, the guide channels and rods are configured to prevent the nut housing from rotating as the actuator actuates;
• and
• a non-rising hollow stem axially coupled to the stem end of the nut housing configured to pass the screw shaft as the nut housing moves along the screw shaft and wherein the nut housing and rods are configured to shield the non-rising hollow stem from the transfer of a torque force caused by the rotation of the planetary roller screw.
