used in high vibration/shock environments), the load which is
applied to the shaft by the vibrations/shocks will be increased by
the weight of the coupling device.
transmission torque surplus relative to the sensor shaft's torque.

Precaution
The selection of a larger
coupling than necessary
will increase the shaft load
which is caused by the
mounting error amount.
Excessive force applied
to the shaft can deform
the coupling and reduce
durability.
