1. A coupling load measurement method for measuring load between a first driving shaft, and a second driven shaft connected by hub coupled both with the first shaft and with the second shaft at least one flexible coupling element coupled to the hub and to the first shaft and/or to the second shaft, the method comprising;
during operation of the shafts, measuring a distance variation in respect to a reference distance between a first flange of the hub and a second flange of the flexible coupling element; and
using the measured distance variation for calculating the load,
wherein the measurement is effected by at least one measuring station.
