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 (82, 84); 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 (82, 84), wherein the at least one compression tool kit comprises: a compression stud configured for passing through two aligned fourth bores (87, 88) of the two components (4, 10), the compression stud having a threaded end-section corresponding to an inner threading of one of the two fourth bores (87, 88); a compression actuator configured for being attached to the compression stud and creating a compression load between the two components (4, 10) when being actuated, a block comprising at least two through holes (22, 23), wherein the compression stud is configured for passing through a first through hole of the at least two through holes (22, 23) in the block; at least one fastening bolt configured for passing through a second through hole of the at least two through holes (22, 23) in the block and a fifth bore (89, 91) of one of the two components, the fifth bore (89, 91) being adjacent to one of the fourth bores (87, 88); 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 (89, 91); 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. a block comprising at least two through holes (22, 23); an alignment bolt configured for passing through a first through hole of the at least two through holes (22, 23) of the block and through two aligned first bores (80, 81) of the two components (4, 10);
