Patent ID: 7625017

Claim:
A coupling assembly, comprising: an arcuate first component defining a radial direction and having a first end with a first mating surface and an adjacent projection and a second end with a second mating surface and an adjacent recess, the first and second mating surfaces disposed radially outward from the projection and recess; and an arcuate second component having a first end with a first mating surface and an adjacent recess and a second end with a second mating surface and an adjacent projection, the first and second mating surfaces disposed radially outward from the projection and recess, the first and second components having a proper alignment in which the first mating surface and the projection of the first component is disposed proximate to the first mating surface and the recess of the second component, and the second mating surface and the recess of the first component is disposed proximate to the second mating surface and the projection of the second component, the first and second components having an improper alignment in which the projection of the first component is disposed to abut the projection of the second component, and the recess of the first component is disposed proximate to the recess of the second component, each end of the first and second components having an extension disposed radially outward from the first or second mating surfaces, a bolt hole wall disposed within the extension and defining a bolt hole through the extension, the bolt holes of proximate ends disposed to form a common bolt pathway when the first and second components are in the proper alignment and disposed to not permit the formation of the common bolt pathway when the first and second components are in the improper alignment; and at least one bolt assembly having a bolt, the bolt extending fully through the bolt hole of the first component and extending partially into the corresponding bolt hole of the second component, the bolt abutting the bolt hole wall of the second component and not extending fully through the first and second components when the first and second components are in the improper alignment.
