1. A system for repositioning two components of a wind turbine with respect to each other, the two components being connected to each other by a bolted joint and the system having at least one alignment tool kit in combination with or alternatively at least one compression tool kit, wherein the at least one alignment tool kit comprises:
a block having at least two through holes;
an alignment bolt configured for passing through a first through hole of the at least two through holes of the block and through two aligned first bores of the two components;
at least one fastening bolt configured for passing through a second through hole of the at least two through holes of the block and a second bore of one of the two components, the second bore being adjacent to one of the first bores;
at least one expandable bush configured for surrounding the at least one fastening bolt and configured to be inserted together with the at least one fastening bolt into the second bore; and
at least one nut configured for at least partial insertion into the expandable bush and having an inner threading corresponding to an outer threading of the at least one fastening bolt such that the at least one fastening bolt may be fastened to the at least one nut inside of the expandable bush and the second bore,
wherein the at least one compression tool kit comprises:
a compression stud configured for passing through two aligned fourth bores of the two components, the compression stud having a threaded end-section corresponding to an inner threading of one of the two fourth bores;
a compression actuator configured for being attached to the compression stud and creating a compression load between the two components when being actuated, a block comprising at least two through holes, wherein the compression stud is configured for passing through a first through hole of the at least two through holes in the block;
at least one fastening bolt configured for passing through a second through hole of the at least two through holes in the block and a fifth bore of one of the two components, the fifth bore being adjacent to one of the fourth bores;
at least one expandable bush configured for surrounding the at least one fastening bolt and to be inserted together with the at least one fastening bolt into the fifth bore; and
at least one nut configured for insertion into the expandable bush and having an inner threading corresponding to an outer threading of the at least one fastening bolt such that the at least one fastening bolt may be fastened to the at least one nut inside of the expandable bush and the fifth bore.
