The micro mechanical device to be tested is held by a clamping
device which is directly mounted on the torque sensor.
This entire set-up is fixed on a xyz translation table to make
the correct alignment to the master motor on top of the setup.
This master motor is equipped with an incremental encoder
of 360 impulses per revolution and drives the micro
mechanical device using a special micro coupling being
rigid for torsion, but elastic for all other degrees of freedom.
