Abstract
A rotary actuator has a driven element including a plurality of recesses that are spaced in a circumferential arrangement around an axis of rotation of the driven element by a spacing angle, and first, second and third latch elements that are each movable between a retracted position, and an extended position in which it is engageable with a corresponding one of the recesses. Sequential movement of the first, second and third latch elements between retracted and extended positions causes rotation of the driven element.
