摘要

The device (5) has an inner portion (8) and an outer portion which are designed as ring segments. The radial outer surface of the inner portion is surrounded by the outer portion. The both circumferential end areas of the outer portion are coupled with end portions of the inner portion by coupling units. The coupling units are fixed at different positions on the end portions of the inner and outer portions along the circumferential direction relative to one another.
