#This application is the divisional application of patent application Ser. No. 10/091,410 and the material contained in the parent application is hereby incorporated herein by this specific reference. This invention relates to the design of a pin clutch to allow for coupling of a rotational shaft to an output mechanism in a synchronous fashion. Specifically, this is related to impacting or operations requiring intermittent or semi-intermittent coupling of an input mechanism or shaft to an output mechanism or shaft. Devices of this nature include fastening tools, throwing mechanisms and other devices in which input energy is built up during a portion of a cycle followed by the coupling and release of that energy to an output mechanism. This invention relates generally to portable electromechanical devices. Such devices are typically less than 30 pounds and are completely suitable for an entirely portable operation.
