Abstract
A torque wrench is presented having a pair of clutches in series. One clutch is a one way clutch, preferably reversible, which transmits the input force in one direction during torquing operations; and the second clutch provides friction restraint against movement in the opposite direction. When desired, force applied to the wrench in the opposite direction overcomes the friction clutches to release the wrench from the work.
