What Steve says makes complete sense. I do put that much torque (I think I may try reducing it a bit as Steve advises). To enable me to hold down the socket I place a broom handle between the fork legs and under my armpit to keep both hands free. For control I use a long breaker handle to loosen and a 1/2 in torque wrench to tighten. I think you can buy flat sockets by the way and Wolf Tooth make a flat ring spanner expressly for this job, epensive mind.Building on what @KennyB said, when you use the socket make sure that you hold it down firmly onto the top cap and apply your torque slowly and carefully. There is not much depth to the alloy top cap and if you round it out you are screwed!
The fastening torque that I saw listed was 40Nm. Wow, that is a lot of torque, same as a BB! I was sure that I hadn't had to apply that much to release it, so I wasn't about to use that much to fasten it in case I damaged the top cap. I tightened it to what felt right and then monitored my fork pressure over the next few rides. I was slowly losing pressure, so I undid the top cap, re-greased the seal and then tightened it a little bit more. No further trouble.
Just checked , both my Yari and Lyrik manuals give 28Nm as the tightening torque.Building on what @KennyB said, when you use the socket make sure that you hold it down firmly onto the top cap and apply your torque slowly and carefully.

Good challenge! The figure I mentioned was a for a Rockshox Pike that came with a 2015 YT Capra. There is every reason to assume that a Pike would be the same as the Yari and the Lyric. I can no longer remember where I got the figure of 40Nm from. What I can remember is thinking wow that's the same as the BB! (which is 40Nm). So maybe the source I accessed, via the internet of course, was just plain wrong. But there was no way I was going to tighten that low profile alloy hex nut to 40Nm, - or 28Nm either for that matter! Common sense rules OK!Just checked , both my Yari and Lyrik manuals give 28Nm as the tightening torque.
