Abstract
A screw driving tool includes a torque output element which defines an axis and is mounted in a housing, a torque transmission section with a plurality of depressions, and a torque transmission element, which is pretensioned by the force of a force accumulator and engages into at least one of the depressions, for coupling the torque transmission section to the housing so as to transmit a torque. The coupling is released when the torque transmission element leaves the depression in an edge-controlled manner against the force of the force accumulator, which is adjustable by an adjustment device, when a limit torque is exceeded. A switchover element is movable from a release position into a blocking position and allows the torque transmission element to leave the depression in the release position but blocks the torque transmission element in the blocking position.
