Mating an engine to a transmission it never came with is the central problem of any drivetrain swap, and the adapter is what solves it. This piece indexes the transmission to the engine bellhousing so the input shaft runs true to the crankshaft centerline, which is what protects the pilot bushing, front bearing, and clutch from the misalignment wear that ends swaps early.
