Method and apparatus are disclosed for advancing and retracting a torque applying tool to and from an operative position. The disclosed apparatus, which includes a push button retracting mechanism, includes structure for transmission of bidirectional torque between its housing and the tool. Screwdrivers and other torque applying tools may thus be driven by rotation of the apparatus housing.
