Abstract

The invention is based on a device for handheld power tool for detecting a torque, having at least one sensor unit. It is proposed that the sensor unit is intended for detecting a deformation parameter. The sensor unit has at least one sensor element that is embodied as a strain gauge. A gearbox is provided which has a bearing location for receiving a deformation element of the sensor unit. An electronic unit evaluates detected data from the at least one sensor unit.
