Abstract

The invention relates to a screwdriver system having a plurality of screwdriver actuation elements (1a-1c), which in each case comprise a torque limitation device that is adjusted to a fixed trigger torque, and having a plurality of screwdriver output elements (2a-2b) that comprise a screwdriver output profile (3a-3c) for the torque-transmitting engaging on a corresponding counter profile of a screw head, and having a coupling profile (4a-4c) for the torque-transmitting coupling to a coupling counter profile (5a-5c) of one of the screwdriver actuation elements (1a-1c). According to the invention, to protect against misuse, one or more first screwdriver output elements (2a-2c) comprise a first coupling profile (4a-4c), at least one or more second screwdriver output elements (2a-2c) comprise a second coupling profile (4a-4c), one or more first screwdriver actuation elements (1a-1c) that are adjusted to one first trigger torque, comprise a coupling counter profile (5a-5c) that can only be coupled to the first coupling profile (4a-4c) and that at least one or more second screwdriver actuation elements (2a-2c) that are adjusted to a fixed second trigger torque that is different from the first, have a coupling counter profile (5a-5c) that can only be coupled to the second coupling profile (4a-4c).
