1. An air turbine starter comprising: a turbine including a turbine wheel with a plurality of turbine blades and a turbine rotor shaft coaxial with said turbine wheel;a gear mounted to said turbine rotor shaft, said turbine rotor shaft and said gear define a connection comprising: a first interference fit;a second interference fit; andan interface axially between and adjacent to said first interference fit and said second interference fit, wherein in said interface said turbine rotor shaft engages and rotationally locks with said gear such that through said interface said rotor shaft is operable to transfer torque to said gear. 2. The air turbine starter as recited in claim 1, wherein a pilot diameter of said first interference fit is larger in diameter than a pilot diameter of said second interference fit. 3. The air turbine starter as recited in claim 1, wherein a pilot diameter of said first interference fit is larger in diameter than a major diameter of said interface of said turbine rotor shaft and a pilot diameter of said second interference fit is smaller than said major diameter of said interface. 4. The air turbine starter as recited in claim 1, further comprising a component mounted to said turbine rotor shaft to abut said gear and a nut mounted to said turbine rotor shaft to abut said gear, said nut operable to axially drive said gear toward said component. 5. The air turbine starter as recited in claim 1, wherein said gear includes: a gear inboard pilot diameter;a gear outboard pilot diameter;a spline minor diameter axially between and adjacent to said gear inboard pilot diameter and said gear outboard pilot diameter. 6. The air turbine starter as recited in claim 5, wherein said gear inboard pilot diameter is greater than said gear outboard pilot diameter. 7. The air turbine starter as recited in claim 5, wherein said gear outboard pilot diameter and said gear inboard pilot diameter each define an inner diameter. 8. The air turbine starter as recited in claim 5, wherein said turbine rotor shaft includes: a turbine rotor shaft inboard pilot diameter;a turbine rotor shaft outboard pilot diameter;a spline major diameter axially between and adjacent to said turbine rotor shaft inboard pilot diameter and said turbine rotor shaft outboard pilot diameter. 9. The air turbine starter as recited in claim 8, wherein said turbine rotor shaft inboard pilot diameter is greater than said turbine rotor shaft outboard pilot diameter. 10. The air turbine starter as recited in claim 9, wherein said turbine rotor shaft inboard pilot diameter and said turbine rotor shaft outboard pilot diameter each define an outer diameter. 11. The air turbine starter as recited in claim 1, wherein said gear is a sun gear of a planetary gear system. 12. The air turbine starter as recited in claim 1, wherein said first interference fit is an interference between a gear inboard pilot diameter of said gear and a turbine rotor shaft inboard pilot diameter of said turbine rotor shaft, and said second interference fit is an interference between a gear outboard pilot diameter of said gear and a turbine rotor shaft outboard pilot diameter of said turbine rotor shaft, said gear inboard pilot diameter is greater than said gear outboard pilot diameter, and said turbine rotor shaft inboard pilot diameter is greater than said turbine rotor shaft outboard pilot diameter. 13. The air turbine starter as recited in claim 12, wherein said interface is a splined interface. 14. The air turbine starter as recited in claim 1, wherein said first interference fit and said second interference fit bound, respectively, opposed axial ends of said interface. 15. The air turbine starter as recited in claim 1, wherein said interface is a spline. 16. The air turbine starter as recited in claim 1, wherein said first interference fit and said second interference fit are each non-splined. 17. The air turbine starter as recited in claim 1, wherein said gear is a sun gear in a planetary gear system. 18. The air turbine starter as recited in claim 17, further comprising a starter output shaft, and said rotor shaft operable to rotate said starter output shaft through said planetary gear system.
