Problem with pymodbus - ModuleNotFoundError: No module named 'pymodbus.client.sync'

[stsxbel]

Good afternoon. I installed a new server, installed pymodbus via pip, uploaded my scripts that worked on the old server, but when I start it, I get an error: ModuleNotFoundError: No module named 'pymodbus.client.sync'

import pymysql.cursors
from pymodbus.client.sync import ModbusSerialClient
from pymodbus.exceptions import ModbusIOException
