Advantageously, a distance between the coupling interfaces and a cutting edge of the working tool that is advantageous for oscillatory excitation can be provided irrespective of the coupled tool receiver.
It is also proposed that the coupling interface and the further coupling interface be arranged in such a manner that the coupling interface and the further coupling interface can be coupled to a power tool in mutually antiparallel coupling directions.

Preferably, the shaped portion of the main body, in particular along the direction that is parallel to the coupling planes, is arranged between the coupling interface and the further coupling interface. In particular, the main body in the shaped portion extends transversely with respect to the plane of main extent of the receiving region and/or to the coupling planes. In particular, the main body in the shaped portion extends at an angle of at least 5°, preferably at least 10°, particularly preferably at least 20° and very particularly preferably at least 30° relative to the plane of main extent of the receiving region and/or to the coupling planes.
