A coupling assembly for coupling a swivel castor wheel to an object which is to be moved across a surface. In use, an orientation of the swivel castor can be adjusted in order to change a direction of travel of the object across the surface. One disclosed coupling assembly 10 comprises a first coupling component 18 which can be mounted to one of a swivel castor wheel (figure 1, 12) and an object (figure 1, 8), and a second coupling component 20 which can be mounted to the other one of the swivel castor wheel and the object. The coupling components are arranged so that they can rotate relative to one another about a common rotation axis 22, to facilitate adjustment of the orientation of the swivel castor wheel relative to the object. The coupling components are arranged so that, in use, they are biased under the action of gravity towards at least one predetermined rotational orientation relative to one another, to provide a directional bias in the orientation of the swivel castor wheel with respect to the object and so direction of travel of the object across a surface.
