An actuator for a drive apparatus, the actuator comprising:

• a housing defining a space;
• first and second gears disposed in the space;
• and
• a clutch assembly comprising:
• a support shaft disposed in the space and rotatably supporting the first and second gears;
• at least one pin slidably extending through the first gear;
• a spring to urge the at least one pin into engagement with the second gear;
• a clutch shaft support screw extending through an opening in the housing, the clutch shaft support screw comprising a distal portion and a distal end, both disposed external to the housing, and a proximal portion and a proximal end, both disposed in the space, the proximal end having a bore formed therein to retain the support shaft;
• and
• a washer slidably disposed about the support shaft between the spring and the proximal end of the clutch shaft support screw;
• wherein rotation of the clutch shaft support screw adjusts the compression of the spring.
