1. A pinned joint to couple a first section of a gas turbine to a second section of the gas turbine, the pinned joint comprising:
a first mating surface disposed radially about the first section;
a second mating surface disposed radially about the second section and circumferentially around the first mating surface, the first mating surface and the second mating surface joined via a plurality of pins, wherein the coupling of the first mating surface to the second mating surface enables the first section to rotate about the pinned joint during operation of the gas turbine,
a ring disposed between the first mating surface and the second mating surface;
a first pin coupling the first mating surface to the ring; and
a second pin coupling the second mating surface to the ring.
