ABSTRACT:
A coupling used between a handle and a tool having outwardly-opening tool-receiving sockets at its opposed ends for selectively receiving a tool shank and a separate intermediate torque-applying sleeve having outwardly-opening sockets at its opposed ends for selectively receiving a driving handle shank after it is passed through the cooperative tool socket. A pair of reversely-wound springs surround the sleeve and when the handle shank is in one end socket of the sleeve and is turned in one direction, it will drive the tool socket at the other end, but the handle shank and socket can be freely turned in a reverse direction.
