Patent ID: 8539997

Claim:
A filling head for filling in a fluid into a filler neck of a tank ( 14 ), comprising: a rotary connecting element ( 26 ) to form a mechanical connection with the filler neck of the tank ( 14 ) by means of rotation, and comprising a rotatable operating part ( 30 ) for rotating the rotary connecting element ( 26 ), wherein the operating part ( 30 ) is coupled to the rotary connecting element ( 26 ) by means of a torque-limiting coupling device ( 32 , 132 ) that, given a threshold torque, is triggered at least in one direction of rotation and decouples the rotatable operating part ( 30 ) from the rotary connecting element ( 26 ), characterized in that a sensor ( 41 , 141 ) is provided to detect the triggering of the torque-limiting coupling device ( 32 , 132 ) and to send a release signal for indicating that the mechanical connection has been established.
