Abstract
A clutch has a rotatable input, a rotatable output, a spring and a damper mechanism. The rotatable input is capable of being rotated and of being held stationary. The spring is coupled to the input such that each time the input changes modes the spring changes states. The damper mechanism allows the spring to change states without rotating the input. The rotatable output is positioned relative to the spring such that the output synchronously rotates with the input when the spring is in the first state and rotates independently of the input when the spring is in the second state.
