The present invention describes a coupling device ( 1 ) for providing at least two different connection configurations, the coupling device ( 1 ) including at least one first portion ( 3, 7 ) which is provided with a number of first coupling elements ( 33, 77 ), and at least one second portion which is provided with a number of second coupling elements (I-VIII) which are complementary to said first coupling elements ( 33, 77 ), a first connection being provided when said at least one first portion ( 3, 7 ) is in a first coupling configuration with said at least one second portion ( 5 ), at least one of said at least one first portion ( 3, 7 ) and said at least one second portion ( 5 ) being arranged to be disengaged from the corresponding at least one second portion ( 5 ) or the at least one first portion ( 3, 7 ) and selectively be rotated relative thereto to be reengaged thereafter with the corresponding at least one second portion ( 5 ) or at least one first portion ( 3, 7 ) for the provision of another coupling configuration. The invention also describes a method of using the coupling device and the use of the coupling device for the provision of two or more coupling configurations.
