An attachment device for coupling one or more restrained members to a frame. In at least one embodiment, the attachment device may be configured to attach one or more turbine combustor liners to a carrier. The attachment device may include a body rotatable about an axis of rotation and including one or more arms for grasping an edge of at least one restrained member. A fastener may be coupled to the body for coupling the body to a frame. The attachment device may also include a retainer for preventing the fastener, which may be a threaded bolt, from becoming disengaged from the attachment device and traveling downstream in a turbine. An alignment device may be included for facilitating rotation of the body of the attachment device and engagement the arms with edges of retrained members. The alignment device may include an alignment indicator indicating a position of the arms.

We claim: 1. An attachment device, comprising: a body rotatable about an axis of rotation and having at least one cavity for receiving at least one fastener; the at least one fastener positioned in the at least one cavity and coupled to the body; a retainer for preventing the fastener from becoming disengaged from the body; and at least one arm extending from the body and configured to grasp an edge of a restrained member after the body has been rotated about the axis of rotation; a rotation limiting device for preventing the body of the attachment device from rotating about the axis of rotation after the at least one arm has been placed in contact with a restrained member and the rotation limiting device has been engaged; and wherein the rotation limiting device comprises an outer surface of the body configured to prevent rotation of the body about the axis of rotation when the body of the attachment device is placed in a cavity having an inner surface shaped substantially similar to the outer surface of the body. 2. The attachment device of claim 1, wherein the retainer comprises a flange coupled to a bottom portion of the body. 3. The attachment device of claim 2, wherein the flange is threadably coupled to the body and further comprises a welded joint for securing the flange to the body. 4. The attachment device of claim 1, wherein the at least one arm comprises two arms coupled to the body on opposite sides of the body. 5. The attachment device of claim 1, wherein the at least one cavity in the body extends through the body along the axis of rotation. 6. The attachment device of claim 1, further comprising at least one alignment device for receiving an alignment tool to rotate the body, thereby allowing the at least one arm to contact a restrained member. 7. The attachment device of claim 6, wherein the alignment device comprises at least one keyway for receiving a key of an alignment tool. 8. The attachment device of claim 6, wherein the alignment device comprises at least one key for receiving a keyway of an alignment tool. 9. The attachment device of claim 6, further comprising an alignment indicator for indicating a position of the at least one arm. 10. The attachment device of claim 1, wherein the rotation limiting device comprises at least one substantially flat surface forming the outer surface of the body. 11. The attachment device of claim 1, wherein the rotation limiting device comprises a fitting coupled to a bottom surface of the body and having a hexagonal shaped cross-section. 12. The attachment device of claim 1, further comprising an orifice in the fastener extending through the fastener substantially along a longitudinal axis of the fastener for cooling at least a portion of the alignment device. 13. The attachment device of claim 1, further comprising a biasing mechanism for biasing the at least one arm to an open position. 14. The attachment device of claim 13, wherein the biasing mechanism comprises at least one spring positioned proximate to a bottom surface of the body. 15. A liner retainer, comprising: a body rotatable about an axis of rotation and having a cavity extending through the body substantially along the axis of rotation; at least one fastener positioned in the at least one cavity and coupled to the body; a retainer for preventing the fastener from becoming disengaged from the body; at least one arm extending from the body and configured to grasp an edge of a turbine combustor liner after the body has been rotated about the axis of rotation; a rotation limiting device for preventing the body of the attachment device from rotating about the axis of rotation after the at least one arm has been placed in contact with a restrained member and the rotation limiting device has been engaged; at least one alignment device for receiving a tool to rotate the body and contact the at least one arm with a restrained member; and wherein the rotation limiting device comprises at least one substantially flat surface on an outer surface of the body configured to prevent rotation of the body about the axis of rotation when the body of the attachment device is placed in a cavity having an inner surface shaped substantially similar to the outer surface of the body. 16. The liner retainer of claim 15, further comprising an orifice in the fastener extending through the fastener substantially along a longitudinal axis of the fastener for cooling at least one outermost surface of the alignment device.
