主权项 1. A handheld drill/driver device, comprising: a mechanical torque coupling to limit a maximum torque that can be transmitted to an insertion tool, the mechanical torque coupling being configured to modify the limiting torque that can be transmitted to the insertion tool as a function of an operator input via a first operating arrangement; at least one monitoring unit to electrically output a torque characteristic quantity that is a function at least of a torque transmitted to the insertion tool; a drive unit; and a control unit to shut off the drive unit as a function of the torque characteristic quantity of the monitoring unit, and of an operator characteristic quantity, wherein the operator characteristic quantity is a maximum torque outputted by the drive unit and is defined by an operator input via a second operating arrangement, the maximum torque outputted by the drive unit being greater than the limiting torque set at the mechanical torque coupling, wherein the monitoring unit is configured to determine the torque characteristic quantity from at least one characteristic quantity of an energy supply of the drive unit, wherein the torque characteristic quantity is substantially proportional to a momentary torque of the drive unit, wherein the control unit compares the torque characteristic quantity to the operator characteristic quantity and shuts off the drive unit if the torque characteristic quantity exceeds the operator characteristic quantity.
