Screwdriver handle

A screwdriver includes a handle having a longitudinal axis. At the one end of the handle, the screwdriver includes a bit holder extending in the direction of the longitudinal axis or a screwdriver blade extending in the direction of the longitudinal axis. The screwdriver is further includes a drive mechanism in the handle. The drive mechanism causes a bit holder in the handle or the screwdriver blade opposite the handle to rotate. The drive mechanism includes a motor and a freewheel through which the motor can be coupled to the bit holder or the screwdriver blade. The freewheel is designed to relieve the torque when manual torque is introduced into the bit holder or the screwdriver blade through the handle. The drive mechanism further includes a torque limiter for limiting the drive torque of the motor on the bit holder or the blade.
