Some general aspects of the invention provide a device (151, 152, 114) for adjustment of a pivotally mounted rotor blade (101) of a wind energy converter. The device comprises a first drive (151) and a second drive (152) that cooperate to turn the rotor blade (101) between an operating position and a feathered position. The device further comprises a first activatable lockout (191) connected to the rotor blade (101), which in an activated state prevents turning of the rotor blade (101) into the operating position, but allows turning of the rotor blade (101) into the feathered position. Under further aspects, the invention provides a wind energy converter comprising the device (151, 152, 114) and a method for adjusting a rotor blade (101), which is pivotally mounted on a rotor hub (103) of a wind energy converter.
