25299-17 ABSTRACT An apparatus for transmitting signals that can be broken down into at least one AC voltage component between a rotor and a stator from a sender unit to a receiver unit, with the help of annular coils, the coil windings of which form components of the sender or receiver unit, and which are arranged coaxially to the axis of rotation of the rotor and inductively coupled is to be developed so as to generate measured values that are associated with the rotational speed. According to the present invention, this is done in that at least one pair of annular coils is provided for supplying voltage to components on the rotor; in that at least one additional pair of annular coils is provided for the transmission of values that are to be measured on the rotor by means of a measuring system, from the rotor to the stator; in that a sensor element for scanning the rotational speed of the rotor is provided; and in that a switch- ing unit is provided, with the help of which the measured values associated with the rotational speed of the rotor can be further processed or displayed.
