1. A turbine engine, comprising: a bearing housing having a passage along an axis of rotation of a shaft;a cooling gland configured to transfer cooling fluid to the passage; anda mounting structure configured to mount the cooling gland substantially in-line with the passage, wherein the cooling gland is spaced apart from the bearing housing. 2. The turbine engine of claim 1, wherein the mounting structure directly couples the cooling gland to the bearing housing. 3. The turbine engine of claim 1, comprising one or more shims or guides between the bearing housing and the mounting structure configured to align the cooling gland with the passage. 4. The turbine engine of claim 1, comprising one or more rabbets configured to align the bearing housing. 5. The turbine engine of claim 1, wherein the mounting structure and the cooling gland are separable from one another. 6. The turbine engine of claim 1, wherein the mounting structure and the cooling gland are integral with one another. 7. The turbine engine of claim 1, comprising a compressor, a combustor, a turbine, or a combination thereof, coupled to the bearing housing and/or the cooling gland. 8. A system, comprising: a bearing housing for a rotor having a passage along an axis of rotation of a shaft; anda cooling gland configured to transfer cooling fluid to the passage, wherein the cooling gland is coupled to the bearing housing, and wherein the cooling gland is mechanically spaced apart from the bearing housing along the axis of rotation. 9. The system of claim 8, wherein the cooling gland is coupled to the bearing housing substantially in-line with the passage. 10. The system of claim 8, wherein the cooling gland is mechanically spaced apart from the bearing housing by one or more rib structures. 11. The system of claim 8, wherein the cooling gland is configured to interface with one or more coolant pipes for providing the cooling fluid to the cooling gland. 12. A system, comprising: a cooling gland configured to transfer cooling fluid to a passage of a rotor;a mounting structure comprising: an attachment portion configured to mount to a rotor bearing housing;a support portion configured to hold the cooling gland; andan offset portion coupled to the attachment portion and the support portion configured to space the cooling gland axially apart from the rotor bearing housing. 13. The system of claim 12, wherein the support portion comprises an annulus. 14. The system of claim 12, wherein the support portion comprises one or more support ears. 15. The system of claim 12, wherein the offset portion comprises one or more ribs. 16. The system of claim 15, wherein the ribs are spaced about a circumference of the attachment portion to define one or more cutout portions such that a ratio of a surface area of the cutout portions relative to a surface area of the ribs is greater than about 2:1. 17. The system of claim 12, wherein the attachment portion comprises an annulus. 18. The system of claim 12, wherein the attachment portion comprises predrilled fastener holes that are configured to mate with corresponding holes on the rotor bearing housing. 19. The system of claim 18, wherein the predrilled fastener holes are configured to align the mounting structure and the rotor bearing housing so that the cooling gland is coaxial with the passage.
