Abstract: Arrangement for coupling first component and a second component exhibiting thermal expansion. The shank of a fastener extends through the first opening of a flattened first spacer, a spring opening of a spring element, and a second opening of a second spacer element, and is fixedly secured to the first component. The second spacer is disposed within a channel in the second component. The first spacer is disposed subjacent a head of the fastener, and the spring element is disposed between the first spacer and an abutment surface of the second component.
