1. A tool basic module for use with at least one attachment device, said tool basic module comprising:
a drive unit;
a main output shaft having a shaft receptacle configured to at least in part receive a main input shaft of the attachment device; and
a coupling device including:
a mechanical interface on the main output shaft configured to mechanically link to the attachment device in terms of drive technology; and
an electrical interface configured to transmit at least one of an electric output and an electric current to the attachment device,
wherein the mechanical interface is at least substantially cylindrical and has a plurality of form-fitting elements disposed uniformly on an external circumference of the mechanical interface, the form-fitting elements configured to support a torque of the attachment device, and
wherein all interface elements of the mechanical interface and of the electrical interface are at least in part disposed in a plane that intersects the shaft receptacle and runs at least substantially perpendicular to the main output shaft.
