coupling module with the cabin in accordance with fig1 it can be recognized in this respect that the coupling module has a pivot frame 27 with the pivot frame 27 being connected to the adapter frame 28 of the cabin 2 by the pivot apparatus 42 of the pivot device 40 referring now to fig3 it can be recognized that the coupling module 20 in detail comprises a coupling module head part 26 and a coupling module base part 32 which are both releasably connected to one another which will be looked at in more detail at another point the coupling module head part 26 comprises the two head part limbs 34 which are connected to one another by the ceiling web 38 the coupling module base part 32 which is shown partially stripped has the two base part limbs 36 with the base part limbs 36 being releasably connectable to the head part limbs 34 each base part limb 36 forms together with the head part limb 34 the limb 24 of the coupling module 20 that is the coupling module limb the base part limbs 36 of the coupling module 20 are connected by the floor web 39 as in particular results in the view of fig7 reference is made to fig5 in the following for the divisibility of the coupling module head part from the coupling module base part it can be recognized from this that the head part limb 34 of the coupling module head part 26 has a first coupling plate 37 a and the base part limb 36 has a second coupling plate 37 b the head part limb 34.
