Abstract: The invention relates to an apparatus for the transmission of data and energy between two objects moving relative to one another about a common axis of rotation. The objects each comprise coils which are disposed opposite and are spaced apart axially with respect to the axis of rotation such that an energy transmission between the coils is possible by inductive coupling. A respective electrode carrier having a respective electrical conductor is provided coaxially to and rotationally fixed with respect to the respective coils, wherein the electrode carriers are disposed opposite and spaced apart axially and the electrical conductors are arranged such that a data transmission between the electrical conductors is possible by electrical coupling. The electrical conductors are circular or part-circular and are concentric to the axis of rotation of the relative movement. In addition, the respective coil windings and electrical conductors are arranged concentric to one another.
