It was the exact opposite of a coup:

“High-ranking cadres are sentenced to severe punishment for corruption. A warning to political opponents, a few weeks before the party congress.

The biggest wave of purges within China's power apparatus in recent years came to a spectacular end on Friday: Sun Lijun, former Deputy Minister of Public Security, was sentenced to death, with the sentence suspended for two years and then commuted to life imprisonment target.”

…Sun is accused of having formed an opposition “clique” as the leading head, which has positioned itself against state & party leader Xi Jinping. Former Minister of Justice Fu Zhenghua, who was also sentenced to life imprisonment for corruption on Thursday, is said to have belonged to the political clique.
…the police chiefs of Shanghai, Chongqing and Shanxi, who were sentenced to long prison terms this week…six leading cadres from the Chinese security apparatus were hit”
