The invention concerns a device for the adjustment of the pitch of a rotor blade of a wind turbine comprising
- a pitch actuator (1) comprising a tube (3) and
- a fixing device (2) comprising
- a first (20) and a second (21) ring-like element,
- each of which is arranged at the tube (3) and each of which is supported towards a respective stopper (10, 11) assigned to the tube (3), and
- clamping means (28, 50, 60) which press the first (20) and the second (21) ring-like element in such a way towards the respective stopper (10, 11) that the fixing device (2) and the tube (3) are substantially non-relocatable relatively to each other.
