Abstract
Wrench device (1) comprising - at least one torque transmission element (2, 2'), - at least one nut (3) which can be positively and rotationally fixedly attached to the torque transmission body (2, 2') at an axial end region (4) of the torque transmission body (2, 2') for the transmission of a torque from the torque transmission body (2, 2') to the nut (3), and - a receiving body (5) which can be coupled or is coupled to a tool for applying a torque, wherein the torque transmission body (2, 2') is designed at its other axial end region (6) for the positive locking and rotationally fixed reception of the receiving body (5), characterized by that both the at least one torque transmission body (2, 2') and the nut (3) have a central bore (7, 8), wherein the central bores (7, 8) in the torque transmission body (2, 2') and in the nut (3) are aligned along a longitudinal axis (L) of the wrench device (1).
