Embodiments generally relate to devices for compensating for the roll of a fifth-wheel coupling, such as on a prime mover towing a semi-trailer. Example embodiments relate to a compensator for a fifth-wheel coupling, the compensator comprising: mounting structure for connecting the compensator to a towing vehicle unit; a first support comprising a first mounting pivot and a first coupling pivot, and a second support comprising a second mounting pivot and a second coupling pivot, the mounting pivots each pivotally connected to the mounting structure, and the coupling pivots each configured to be pivotally connected to the fifth-wheel coupling; and a limit assembly configured to exert a force or moment on at least one of the first and second supports to restrict movement of the supports. A first axis extends through the first mounting pivot and the first coupling pivot, and a second axis extends through the second mounting pivot and the second coupling pivot; so that when in use, the first and second supports are pivotally connected to the fifth-wheel coupling to support and allow movement of the fifth-wheel coupling relative to the mounting structure, an intersection of the first and second axes defines a roll centre about which the fifth-wheel coupling moves, and the first and second supports are aligned respective to each other such that the fifth-wheel coupling is positioned between the roll centre and the mounting structure, so that movement of the first and second supports reduces the rotation transferred to the mounting structure
