description A device (10) for transmitting torque from a drill rig to a drill bit comprises a handle (14) and a tool fitting (13). The handle (14) is constructed by a first outer tapered region, a groove region, and a second outer tapered region, and includes a longitudinal groove. The tool fitting (13) is formed from a base body (41) having a rotary drive region with an outer rotary drive recess, an intermediate element (42) having an inner drive region with an inner rotary drive and an outer drive region with an outer rotary drive recess, and a locking device (43) for locking the tool fitting (13). The outer drive region is provided with an outer rotary drive. In the connected state, the inner rotary drive engages in the longitudinal groove and the outer rotary drive engages in the outer rotary drive groove. A lower rotary drive is arranged on the base surface of the intermediate element (42), which in the connected state interacts with a lower rotary drive groove in the rotary drive region of the basic body (41). 一种用于
