The utility model belongs to the technical field of power transmission, and particularly provides a torque transmission device, a torque output device and a battery replacing robot. The utility modelaims to solve the problem that the power transmission efficiency between a motor and a socket spanner is low when an existing battery replacing robot executes battery replacing operation. The torque transmission device comprises a universal joint, a floating device and a wrench which are connected in sequence. One end, far away from the floating device, of the universal joint is in driving connection with an output shaft of the power device; the floating device comprises a torque input end connected with the universal joint, a torque output end connected with the wrench and a fixed end fixedlyconnected with a shell of the power device, and the torque input end and/or the torque output end can float in the direction perpendicular to power transmission. According to the torque transmissiondevice, when the wrench dev
