Both Amarmani and his wife, Madhumani, had been admitted in a private ward of BRD Medical College since February 26, 2013.
"The action has been taken on directions of the government. The report of the medical board of the college was yesterday sent to the government," Principal BRD College R P Sharma said.
The couple were shifted to the district jail at about 12 noon in a private ambulance.
The trial was shifted from UP to Uttarakhand on the request of Shukla's family. The trial court in Dehradun had held the couple and three others guilty of murder and slapped life sentence on them in 2007.
In July 2012, the Uttarakhand HC upheld the life imprisonment following which they were serving their sentence at Dehradun Jail.
However, Madhumani got herself transferred to Gorakhpur hospital citing an ailment in 2008 and Amarmani followed suit in 2012.
The slain poetess' sister, Nidhi Shukla, had taken up the matter in the court alleging that the couple was not suffering from any ailment.
