Zusammenfassung:	PCT No. PCT/GB91/01593 Sec. 371 Date May 13, 1992 Sec. 102(e) Date May 13, 1992 PCT Filed Sep. 18, 1991 PCT Pub. No. WO92/05402 PCT Pub. Date Apr. 2, 1992.An apparatus for measuring change of position of a rotor in a drive system having a drive rotor and a driven rotor generally concentrically mounted with respect to the drive rotor, the drive and driven rotors being magnetically coupled together. The apparatus includes a conduction device stationarily mounted between the rotors and a device for measuring the EMF (Electro Motive Force) produced in the conduction device as the rotors rotate. The apparatus also includes a device for determining, from the measurement, the relative position of the two rotors and/or the position of one of the rotors.
