Zusammenfassung:The torque-screwdriver is fitted with a claw coupling which operates via a valve a paint marking device when the pre-set torque has been reached. The valve (7) is located near the claw coupling (3). From the valve a channel (8, 8') connects the energy storage space (9) with the tool holder (1) in which the marking device is located. When the teeth of the claw coupling (3) start to glide above each other, a valve (7) is operated. The energy storage space is a compressed air chamber and is located in the handle of the tool. The compressed air chamber can be recharged by a push-on-valve (10) provided in the handle (2) of the tool.
