Wedge torque assembly

An actuator assembly comprising:

• a cam body comprising a hollow body with a cylindrical interior profile, and a first recess defining a first axial cam;
• an indexing nut retained within the cam body, wherein the indexing nut comprises an inner portion proportioned to retain a valve plug, and wherein the indexing nut is rotatable along an axis of rotation of the valve plug and free to reciprocate along an axis of reciprocation;
• an indexing pin attached to the indexing nut, wherein the indexing pin follows a profile of the first axial cam upon rotation of the indexing nut around the axis of rotation;
• and
• an intermediate nut comprising a lower portion detachably connected to the indexing nut and an upper portion detachably connected to a drive screw, wherein the drive screw is retained between the actuator assembly and an adapter plate of an apparatus, the drive screw comprises a key slot for engaging with a drive shaft, and the adapter plate further comprises a mount point for a motor driving the drive shaft.
