A method and an assembly for fastening at least one screw nut (301) to be tightened of a rotor blade bearing (200) of a wind turbine (100) are provided. A screw nut driver assembly (400) is provided at a rotatable portion of the rotor blade bearing (200), the screw nut driver assembly (400) being adapted to automatically tighten the at least one screw nut (301). The screw nut driver assembly (400) is aligned with the screw nut (301) to be tightened by rotating the rotatable portion with a pitch drive (402) of the wind turbine (100). Then the screw nut (301) is tightened using the screw nut driver assembly (400). |
