Abstract: The tool mounting device according to the invention comprises a first and second coupling device, wherein the first coupling device comprises at least one receptacle, the second coupling device comprises at least one receptacle pin, and the first or second coupling device comprises a tool suspension. The receptacle comprises a recess and an opening, wherein the opening extends from the first end in the direction of the second end over a length and the length of the opening is smaller than a length of the recess and a width of the opening is greater than or equal to a width of the receptacle pin.

Abstract: The invention relates to a coupling system, a coupling arrangement, a method for mechanically coupling a coupling system and a method for measuring the mechanical loading of a coupling system. The coupling system according to the invention includes a first coupling part, at least one second coupling part, which can be coupled with the first coupling part by way of at least one coupling, and at least one sensor, wherein the first coupling part has an evaluation unit (5), which can be connected to the at least one sensor for sensing measuring signals, and the measuring signals that are sensed by the evaluation unit (5) can be called up by way of the evaluation unit, wherein the coupling in the coupling area can be checked by means of the at least one sensor.
