Abstract
A device is provided for the adjustment of the pitch of a rotor blade of a wind turbine. The device includes a pitch actuator and a fixing device. The pitch actuator includes a tube. The fixing device includes a first and a second ring-like element, each of which is arranged at the tube and each of which is supported towards a respective stopper assigned to the tube, and a clamping means which press the first and the second ring-like element in such a way towards the respective stopper that the fixing device and the tube are substantially non-relocatable relatively to each other.
