  "textContent": "The device has a coupling support (14) including a coupling arm. A trailer (92) is firmly or movably arranged on a support (11) that is fixed to a towing vehicle (90). A force sensor (30) detects traction and shearing forces for determining a tensile load caused during a traction operation of the trailer of a coupling element (23). The force sensor outputs a force signal for representing the traction and shearing forces. An evaluating unit (50) determines a trailer mass value on the basis the force signal and an acceleration value. Independent claims are also included for the following: (1) a method for determining a trailer mass value of a trailer on the basis a trailer coupling for a towing vehicle (2) an evaluation module.",
