2. The assembly according to claim 1 , wherein the cam surface ( 38 ) is a surface of revolution and wherein in particular the cam surface ( 38 ) is a tapered or conical external surface.

3. The assembly as claimed in claim 1 , wherein the recentring element ( 28 ) is provided with a central bore ( 39 ) and is slidably mobile on a guiding shaft ( 36 ) fixed to the connecting plate ( 12 ).

4. The assembly as claimed in claim 1 , wherein the angle (α) of inclination of the cam surface ( 38 ) and/or of the cam follower surface ( 40 ) in relation to the direction of connecting (Z) is between 30° and 60°.

5. The assembly as claimed in claim 1 , wherein the cam follower surface ( 40 ) cooperates with the cam surface ( 38 ) of the recentring element ( 28 ) in idle position and in offset position of the plate ( 12 ).

6. The assembly as claimed in claim 1 , wherein the cam follower surface ( 40 ) and the cam surface ( 38 ) are complementary, in particular inclined by the same angle (α).

7. The assembly as claimed in any 1 , wherein the recentring element ( 28 ) comprises an extension ( 48 , 50 ), according to the direction of connecting (Z) in relation to the cam surface ( 38 ), forming a guiding surface of the recentring element ( 28 ) according to the direction of connecting (Z).

8. The assembly as claimed in any 1 , wherein the means of elastic recalling include a spring ( 42 ) arranged between the recentring element ( 28 ) and an integral element ( 32 ) of the recentring element ( 28 ) in the plane (X-Y).

9. The assembly as claimed in claim 1 , wherein the connecting plate ( 12 ) is fixed according to the direction of connecting (Z) in relation to the support ( 22 ), to the nearest operating clearances.

10. The assembly as claimed in claim 1 , wherein the connecting plate ( 12 ) and the stop plate ( 32 ) form a floating integral assembly mounted sandwiched around the support ( 22 ).

11. The assembly as claimed in any preceding claim 1 , wherein the means of elastic recalling ( 30 ) are housed at least partially in a recess ( 44 ) of the recentring element ( 28 ).

12. The assembly as claimed in claim 1 comprising, for each recentring element ( 28 ), a guide column ( 34 ) coaxial to the associated recentring element ( 28 ).

13. The assembly as claimed in claim 1 , wherein the support ( 22 ) comprises a surface forming an abutment according to a direction (X, Y) perpendicular to the direction of connecting (Z) to the connecting plate ( 12 ) in relation to the support ( 22 ) in an offset position of the plate ( 12 ).

14. The assembly as claimed in claim 1 , comprising a receiving slide ( 24 ) fixed to the support ( 22 ) extending in the direction of connecting (Z) and adapted to guide the complementary electrical ( 20 ) and/or fluid ( 18 ) connection element to the connection element in the coupling phase.

15. Assembling ( 2 ) of an assembly as claimed in claim 1 and a complementary ensemble ( 6 ), with the complementary ensemble comprising at least one fluid and/or electrical connection complementary with each electrical ( 16 ) or fluid ( 14 ) connection element fixed to a tank ( 8 ) of liquid.
