A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable. 1. A method for providing lateral shifting and articulation capabilities comprising:{'b': 102', '101', '103', '103', '113', '102', '101, 'carrying a primary draft load between a platform () and a base () with a fixed-length link (), said fixed-length link () having a longitudinal axis () running between the platform () and the base ();'}{'b': 115', '102', '114', '101, 'allowing for translation in at least two orthogonal directions of a platform origin () located on the platform () with respect to a base origin () located on the base ();'}{'b': 103', '102', '101', '113, 'restricting rotation of the fixed-length link (), the platform (), and the base () around the longitudinal axis ();'}{'b': 102', '107', '108', '109', '102', '103, 'allowing for rotation of the platform () with variable-length links (, , ) pivotally connected to the platform () and the fixed-length link (); and'}{'b': 101', '104', '105', '106', '101', '103', '102, 'allowing for rotation of the base () with variable-length links (, , ) pivotally connected to the base () and either (a) the fixed-length link () or (b) the platform ().'}2. The method according to further providing indexing capabilities comprising:{'b': 135', '101', '115', '136, 'allowing for rotation of the turntable () attached to the base () on a longitudinal axis ...
