<p>A rotating electrical coupling for machines comprising a fixed part and a rotatable part comprises two electronic cards (51, 52) for modulation, demodulation and management of these signals, of which one is fixed to the fixed part and the other is rotatable with the movable part. Two cards (51, 52) communicate between one another by means of an optical signal beam so as to be uninfluenced by the relative angle between the fixed part and the rotatable part.</p> |
