1. A tightening device for a wind turbine configured to fasten and/or tighten a plurality of fasteners to a target object of the wind turbine, wherein the fasteners are arranged in a circle, the tightening device comprising:
a center bearing unit arranged to permit rotational movement of the tightening device about a center axis that is concentric with an axis of the target object, wherein the center bearing unit is configured to be attached to a surface of the target object of the wind turbine, wherein the center axis is normal relative to the surface of the target object to which the center bearing unit is configured to be attached to;
a torque unit to, in operation, apply torque to the fasteners to fasten and/or tighten the fasteners to the target object of the wind turbine; and
a first arm extending in a radial direction away from the center bearing unit, wherein the torque unit is mounted on the first arm between a first end of the first arm proximate the center bearing unit and a radial outer end of the arm, wherein the first arm is detachably connected to the center bearing unit.
