Attaching the PCB to the sheetmetal cover would remove quite a bit of
freedom for the shafts to be misaligned.

So, how do people make these things work as rotary position sensors?
Is there a mechanical specifications document buried on the MuRata web
site that I'm missing? Is there a cost-effective shaft coupler to be
had that'll couple the angle without coupling off-axis motion?

Can you design so that the sensor is soldered on to the PCB *after* the
shaft is installed? That would remove most of your tolerance buildup.
