Abstract

The present invention relates to a system (S) for measuring the position of a coupling member (1) that comprises a shaft part (2), a first flange (3), a second flange (4) and a first resilient bushing (5), which secures the first flange (3) to the shaft part (2), and a second resilient bushing (6), which secures the second flange (4) to the shaft part (2). Each resilient bushing (5, 6) is arranged with a resilient yield between the respective flange (3, 4) and the shaft part (2). The flanges (3, 4) are intended to be secured to a respective first shaft (7) and second shaft (8). When the coupling member (1) is placed between the first shaft (7) and the second shaft (8), it is intended to transfer a rotation movement from the first shaft (7) to the second shaft (8). The system (S) further comprises at least a first head unit (9) mounted on a first fixture (10), where the first fixture (10) is designed to be mounted between the first flange (3) and the shaft part (2) via existing mounting elements for the first resilient bushing (5). The fixture (10)comprises at least one sensor (15) arranged for position measurement between the first flange (3) and the shaft part (2).
