Abstract
A clutch including an output hub on an output frame, an input shaft on an input frame, wherein the input shaft rotates within a bore in the output hub. An input hub is attached on an end of the input shaft, and a spring engages the input hub and the output hub. A locking spring clamp attaches the spring to the input hub. The input frame and the output frame are adjacent to one another on a side of the clutch opposite the input hub. An electronic control system for the clutch is also described that makes possible the use of the apparatus for electromechanical joint control in an orthotic or prosthetic device.
