Abstract:
An adapter for detachably concentrically coupling shafts having a range of diameters to a rotating input actuator capable of rotating about a rotational axis, comprising:(a) a housing having a hub adapted to be driven by a rotating input and having a housing opening adapted to receive one end of a shaft; (b) a pair of adjustable converging jaw members in the housing for capturing shafts of varying sizes; (c) a self-centering adjustment system for opening and closing the converging jaw members thereby defining a jaw opening therebetween while maintaining the center between the converging jaw members concentric with the rotational axis of said hub; and (d) wherein the clamping force to transfer rotational torque between said shaft and said hub is generated independent of said self-centering adjustment system.
